Technical Field

[0002] Wastewater treatment mainly includes sedimentation, filtration, oxidation and other processes, which use physical and chemical means to remove suspended solids, soluble organic matter and heavy metals in sewage. After the sewage enters the sedimentation tank, chemical agents are added to aggregate suspended matter and colloids into large particles to accelerate the sedimentation rate.

[0003] However, in the sewage treatment process, sewage often contains a high concentration of sludge in the initial stage of entering the treatment system. Especially in the process of sewage flowing from the pipeline to the sedimentation tank, the pipeline is very likely to be blocked due to the deposition and accumulation of sludge, which not only affects the smooth flow of sewage, but also may reduce the efficiency of subsequent treatment steps, and even pose a potential threat to the stable operation of the entire sewage treatment process.

When the first rack 83 moves into the third slide groove 48, it meshes with the gear 104 to drive the valve 101 to slide upward to open or close the mud discharge groove 44; and when the first rack 83 on the scraper rod 81 moves into the third slide groove 48, it meshes with the gear 104 to rotate, thereby driving the second rack 102 on the valve 101, causing the valve 101 to slide upward in the fourth slide groove 49, opening the mud discharge groove 44; thereby, the sludge enters the sludge pipe 11 through the mud discharge groove 44, and then is directly discharged into the bottom of the sedimentation tank 1.

[0064] Preferably, see Figure 5 and Figure 7 As shown, a fourth slide groove 49 matching the valve 101 and the second rack 102 is provided at the bottom of the boost pipe 41, and the third slide groove 48 and the fourth slide groove 49 are both T-shaped or L-shaped structures where they are adapted to the first rack 83 and the second rack 102.

[0068] Working principle:

[0069] During specific use, after sewage enters from the water inlet pipe 2, it passes through the boosting groove 42 of the boosting pipe 41. Due to its truncated cone structure, the sewage is gathered and finally flows out through the narrow end drain pipe 43 of the boosting groove 42. The flow rate of the flowing water increases, and then it impacts the water wheel 51 to make it rotate to form a power source; then it is transmitted to the reciprocating screw 91 through the first bevel gear 531 and the second bevel gear 532. Under the limiting action of the limiting rod 92, the slider 66 moves back and forth to squeeze the baffle 62, and then the baffle 62 squeezes the airbag 61; in this way, the airbag 61 extracts the sewage treatment agent from the agent barrel 3 through the drug extraction pipe 63 under the limiting action of the second one-way valve 69, and then the agent is sprayed out through the drug spraying pipe 64 under the limiting action of the first one-way valve 68. The sprayed agent passes through the high-pressure nozzle 65 to impact the stirring water wheel 7. The stirring water wheel 7 further increases its rotation speed under the drive of its own reciprocating screw 91, thereby stirring the sprayed medicine and accelerating the mixing of the medicine and sewage; at this time, the sewage is pre-treated, and the pre-treated sewage is settled in the sludge tank 46, and the scraper assembly 8 on the reciprocating screw 91 moves back and forth under the limiting action of the limiting rod 92 to clean the sludge settled in the sludge tank 46, and when the first rack 83 on the scraper rod 81 moves into the third chute 48, it meshes with the gear 104 to rotate it, thereby driving the second rack 102 on the valve 101, causing the valve 101 to slide upward in the fourth chute 49, opening the sludge discharge chute 44; thereby, the sludge enters the sludge pipe 11 through the sludge discharge chute 44, and then is directly discharged into the bottom of the sedimentation tank 1; it is worth noting that The spacer ring 93 provided on the reciprocating screw 91 is used to separate the threaded sections on the reciprocating screw 91, so that the scraper rod 81 and the slider 66 can perform reciprocating motion respectively, thereby effectively solving the problem of sludge easily accumulating in the water inlet pipe of the existing sewage treatment equipment.
